about:cache is quite all right except for the following:
(a) you don't get history direct, you have to click "List Cache Entries" first;
(b) the cache entries list includes, separately, css-s, gifs and other kinds of files which are not always necessary and which make finding the right history item complicated; there should an option to display "only urls visited" or "all cached files" - that was what I meant under "conversion"; - just to make history presentation user-friendly
(c) the cache entries list includes the size and date etc for every cache item; that is not so necessary, just names (urls) in the list would often be enough.
A good history list is provided e.g. by Opera: it's compact in appearance and lists visited htmls by date (coming first) and then all urls (under that date).
